It's not just you: the weather is getting worse. And if there's one person who would know, it's "America's weatherman," Al Roker, who's spent decades reporting live from some of the worst storms and natural disasters in history. He...

A hydrogen atom is traveling high within the outermost layer of Earth's atmosphere. This particular atom first entered the exosphere millions of years ago, but today it overcomes Earth's gravitational pull and escapes, joining the...

If we're going to solve the climate crisis, we need to talk about supply chains, says biodiversity champion and 2023 Audacious Project grantee Nicole Rycroft. Her organization, Canopy, partners with key industry leaders to overhaul their...

Jellyfish aren't the most nutritious animals in the ocean. Yet sea turtles and many other organisms get their nutrition from almost nothing else. Here's why they don't totally starve to death.

You'd think that the Northern and Southern Hemispheres would be basically symmetrical -- that since our planet is a ball, the climate, temperature, and weather patterns would be the same on top as on the bottom. But there are some...

One reason the Bermuda Triangle has scared people for generations is the seaweed. And thanks to eutrophication and other human causes, that Sargassum seaweed is starting to travel the world. Here's how we're accidentally making more of...

Solving food shortages caused by droughts is a big challenge that may benefit from a tiny ally. Turns out that the microbes living in the soil around plants can give them a boost when water's scarce, which means more food for us, which...

While they are incredible engineering marvels, we don't think about bridges all that much. But there's a good reason we should all be thinking about our bridges, since there's a weird reason that more of them might be at risk of failure...

About 1.8–0.8 billion ago, the Earth went through a period known as the Boring Billion, where not a lot changed in terms of geology, evolution, or even the number of hours in a day. Some scientists call it “the dullest period in Earth’s...

Volcanoes might seem like an unstoppable force of nature - but there is at least one OTHER force on Earth that seems to be able to keep them down.

You might not think of a sea creature as helpful in the prevention of climate change, but sperm whales have been doing their part to cool the planet by doing what most animals do best: pooping.

SciShow’s hot take: Peppers don’t produce that spicy goodness for the reason you think!

On New Year's day, we said goodbye to George the Snail, marking the first extinction of 2019, and the way things are looking, it won't be the last.

When you think about the impact of climate change on the circle of life, you likely picture polar bears or Bengal tigers struggling in new conditions. But the impacts on the world go all the way down to the tiniest creatures who do some...

Thanks to the Monterey Bay Aquarium and their research and technology partner MBARI for partnering with us on this episode of SciShow. They worked together on an exhibition, “Into The Deep: Exploring Our Undiscovered Ocean,” to give...

Scientists who piece together our past can do so through the rare fossil or artifact, or they can go to one convenient location: a hyrax latrine.

Hank gets to the bottom of two studies reporting high sea ice coverage and snowmass in Antarctica in the same year that the Arctic has reported a record low of sea ice. What is going on here?

You might want a really sturdy umbrella to dig into this video, because we’re discussing 5 animals that have a tendency to rain down from the sky and the reasons we think this might be happening!

Humans are great at creating, and solving, problems. Hank talks with Gina McCarthy about the biggest public health problem we face today: climate change. Gina McCarthy is the Director of C-CHANGE (Center for Climate, Health and the...

If salty water is constantly spilling into the world’s oceans, does that mean they are getting saltier by the day?

Dinosaurs were huge—it's common knowledge. So why aren't modern mammals anywhere near that size? In this episode of SciShow, Hank gives a quick run-down of the reasons scientists think the land mammals of today are nowhere near the size...

New research suggests climate change in the past might have helped dinosaurs spread across the world. And modern climate change is revealing some of the things they left behind.

Roots do more than hold plants in place -- they hold the planet in place. They're an important defense against drought and climate change, and of course, our actions are changing them.

How different would things be if Earth had always rotated in the opposite direction? Hosted by: Stefan Chin
